Feasibility Analysis of Surface Rail in the Revitalization of the Railway Road MATEC Web of Conferences 215, 01038 (2018) https://doi.org/10.1051/matecconf/201821501038 ICTIS 2018 Feasibility Analysis of Surface Rail in The Revitalization of The Railway Road Wilton Wahab Institut Teknologi Padang, Department of Civil Engineering, Padang, Indonesia Abstract. The railway lines are an integral construction made of steel, concrete or other construction are located on the surface, below and above ground or dangling along with devices that direct the course of the train. Reflecting on the success of the revitalization of the railway line Padang-Pariaman, PT. Railway DIVRE II West Sumatra recently returned to the revitalization of the railway line Lubuk Alung–Kayu Tanam. In this final project feasibility analysis back to the road construction railroad Lubuk Alung-Kayu Tanam considering this path has not been used and an increase in the construction of the railroad on the route. The methodology used is the collection of data from related parties subsequently perform the calculation and analysis of railroad construction that has been revitalized. Data obtained from the calculation of the voltage rails on existing condition of 1380.34 kg/cm2 and the voltage rails after revitalized by 840.601 kg/cm2 while rail voltage maximum allowed is 1325 kg/cm2, the rail existing deserves to be revitalized. Iron bearing on the condition of the existing able to withstand a load of 6761.69 kg, while the load caused by railbus is 8568.986 kg so that the iron bearing existing not worth traversed railbus axle 18 ton and made improvement to the concrete pads. After upgrading, held their concrete pads capable of 23241.678 kg load and expenses incurred as a result of railbus axle 18 tons of concrete pads amounted to 6986.276. Concrete pads so deserve to be passed railbus axle 18 tons. The results of this thesis states that the construction of a rail road Lubuk Alung-Kayu Tanam deserves to be revitalized because of the condition of the existing construction rails and bearings are not able to withstand the stresses and loads that occur due railbus 18 tons passing through. transportation technology system will also be based on 1 Preliminary improving the quality of human life and the goals of fulfilling the needs of globalization. One example of the Transport has now grown into one of the most basic success of Indonesian transportation technology is the human needs. Starting from the smallest scope of human improvement of railway performance to reduce life, medium scope up to the widest scope. A country congestion due to the increase of private vehicles such with different characteristics of its activities, its culture, as monorail and MRT (Mass Rapid Transit) in Jakarta and its physical, is definitely in contact with [2]. transportation. The effects of the need for West Sumatra as one of the developing provinces in movement/movement of people and goods will cause a Indonesia is also currently being incessant to develop demand for the provision of infrastructure and means of railway transportation mode. As we know that the action to create a movement that goes with the condition railway in West Sumatra had experienced suspended of safe, convenient and smooth, and economical in terms animation until in 2007 the Padang-Pariaman railway of time and cost. In the end, the need for transportation line was reactivated. The success of revitalization is not only a natural need just, but it is necessary to have system and technology of transportation mode of a good system so that the objectives of the above railway transportation of Padang -Pariaman line need to movements can be achieved [1]. The current evolving be fully supported by good infrastructure. Not only the transportation system has embodied a form of ministry Padang - Pariaman railway course, beginning in through various means of mechanistic movement that November 2016 and DIVRE II WEST SUMATERA almost extends to all networks of territory on earth. Thus, also reactivated the Lubuk Alung - Sicincin - Kayu today through modern transportation systems it is not Tanam railway line called the Pioneer Train. The difficult to reach the center of human activity from difference is that if the Padang-Pariaman railway line is different angles of movement. The development of still crossed by BB locomotives, the Lubuk Alung-Kayu transportation technology in the future will be directed Tanam line is crossed by a railbus type train with an axle to the ability to overcome the demands of freight load of 18 tons, where the load is larger than the limitations, mileage, the speed of movement, comfort, locomotive that usually crosses this line is 11 tons.

  • Appendix 1 the Influence of Bushido: Why Japanese Officers Drove Pows to Work Unreasonably Hard
    Appendix 1 The Influence of Bushido: Why Japanese officers drove PoWs to work unreasonably hard Bushido, developed in feudal Japan, still had a strong influence on Japanese officers during World War II. Bushido demanded absolute loyalty and exacted the penalty of suicide (by self-immolation or disembowelment) for a dishonourable result. All the railway officers realised how important the Burma–Thailand Railway was for the survival of the Japanese army in Burma. So they knew if the completion of the railway were delayed and put the Burma army in danger, their regimental commander was sure to commit suicide for the dishonour, and the officer who did not do his part on time and caused the delay should also commit suicide, according to Bushido. This is the main factor which drove the officers to force PoWs to complete the daily quota of their work by all means, as the daily quota was based on the minimum required to complete the railway on time. Thus PoWs were forced to work over the standard work time even in miserable conditions. In the Japanese army, orders are seen as absolute. Lower-ranking officers were not allowed to refuse the order to attack an enemy position. However the orders on engineering projects were flexible because of the nature of the work. The officer who did not complete the work on time might be demoted or at worst fired, never put to death. As an example, the railway regiment commanders did not accept the order to bring forward the completion of the Burma–Thailand Railway by two months, though this could cause demerit in their career.

Resulting landslides left scores of houses and villages buried, whilst disrupting power and communication for days. The first of these events was felt throughout Sumatra and Java, in Indonesia, and in neighboring Malaysia, Singapore and Thailand. The Government of Indonesia responded immediately by declaring a one-month emergency phase, providing emergency relief funds with a promise of more to follow, and indicating that it welcomed international assistance. In addition, tents, blankets, food, medical personnel, emergency clean water facilities and toilets were provided during the immediate response. The armed forces were also engaged in search and rescue operations and delivering relief aid. National partners, including the Indonesian Red Cross, engaged immediately in emergency response efforts. This report describes the human loss, assessment of the damage to physical assets, the subsequent losses sustained across all economic activities, and the impact of the disaster on the provincial and national economies.

  • Indonesia: Transport Sector Assessment, Strategy, and Road Map
    Indonesia: Transport Sector Assessment, Strategy, and Road Map The Asian Development Bank (ADB) is preparing sector assessments, strategies, and road maps (ASRs) to help align future ADB support with the needs and strategies of developing member countries and other development partners. ASRs are working documents that help inform the development of country partnership strategies. This transport sector ASR highlights development issues, needs, and strategic assistance priorities of the Government of Indonesia and ADB, with a focus on roads and inter- and intra-island connectivity. It highlights sector performance, priority development constraints, the government’s strategy and plans, other development partner support, lessons learned from past ADB support, and possible future ADB assistance including knowledge support and investments. The product serves as a basis for further dialogue on how ADB and the government can work together to tackle the challenges of managing transport sector development in Indonesia in the coming years. About the Asian Development Bank ADB’s vision is an Asia and Pacific region free of poverty. Its mission is to help its developing member countries reduce poverty and improve the quality of life of their people. Despite the region’s many successes, it remains home to two-thirds of the world’s poor: 1.8 billion people who live on less than $2 a day, with 903 million struggling on less than $1.25 a day. ADB is committed to reducing poverty through inclusive economic growth, environmentally sustainable growth, and regional integration. Based in Manila, ADB is owned by 67 members, including 48 from the region. Its main instruments for helping its developing member countries are policy dialogue, loans, equity investments, guarantees, grants, and technical assistance.
